Answer:

When y=7,9 the answer is yes when it = -10,-8 the answer is no.

Step-by-step explanation:

Simple substitution gets us the resulting values. for y=7 we get $15\geq 15$ which is true. For y=9 we get $19\geq 15$ which is also true. For the other values we get a negative number which is not a solution.

Lie is solving the quadratic equation by completing the square.

wel

we have

$3x^{2} + 18x - 8 = 0$

Step $1$

Move the constants to the right side

$3x^{2} + 18x = 8$

Step $2$

Factor 3 out of the variable terms

$3(x^{2} + 6x) = 8$

Step $3$

Add $27$ to both sides of the equation

$3(x^{2} + 6x+9) = 8+27$

$3(x^{2} + 6x+9) = 35$

Step $4$

Write the polynomial as a binomial squared

$3(x+3)^{2} = 35$

therefore

the answer is

Factor 3 out of the variable terms.
